Nursing Process Practice Questions

Correct Answer: D

Rationale: The correct answer is D: Pallor, tachycardia, and a sore tongue. Pernicious anemia is caused by a deficiency in vitamin B12, leading to symptoms such as pallor (due to decreased red blood cells), tachycardia (as the heart works harder to compensate for decreased oxygen-carrying capacity of the blood), and a sore tongue (due to inflammation of the tongue). Choice A is incorrect because bradycardia would not be expected in pernicious anemia, and reduced pulse is not a typical finding. Choice B is incorrect because weight gain is not a common symptom of pernicious anemia. Choice C is incorrect because angina and double vision are not typical findings of pernicious anemia, and anorexia is more likely due to other causes.

Correct Answer: D

Rationale: The correct answer is D: Maturates T cells. The thymus gland is crucial for the maturation of T cells, a type of white blood cell that plays a central role in the adaptive immune response. T cells mature in the thymus through a process of selection and education, where they learn to distinguish self from non-self antigens. This process is essential for the development of a functional immune system. Choices A, B, and C are incorrect because the thymus gland does not play a role in the maturation of B cells, platelets, or red blood cells, respectively.

Correct Answer: C

Rationale: The correct answer is C: fluid volume deficit. In diabetes insipidus, there is an excessive amount of dilute urine excreted, leading to dehydration and fluid volume deficit. The posterior pituitary tumor causes a deficiency in antidiuretic hormone (ADH), which regulates water reabsorption in the kidneys. As a result, the client experiences polyuria and polydipsia, leading to fluid volume deficit. Choices A, B, and D are incorrect because diabetes insipidus does not cause fluid volume excess, incontinence, or diarrhea. The key is to recognize the pathophysiology of diabetes insipidus and its impact on fluid balance.

Correct Answer: A

Rationale: The correct answer is A: Ambulating a patient. Direct care interventions involve hands-on activities directly impacting patient outcomes. Ambulating a patient is a direct care intervention as it involves physically assisting the patient to move, promoting circulation, preventing complications, and improving overall well-being. Inserting a feeding tube (B) and performing resuscitation (C) are also direct care interventions as they involve immediate patient care actions. Documenting wound care (D) is not a direct care intervention as it involves recording information about a care activity rather than physically performing the care itself.

Correct Answer: B

Rationale: The correct answer is B because the internal mammary and internal thoracic arteries in the chest are commonly used for grafting due to their size, durability, and long-term patency. These arteries have a better track record for successful grafting procedures compared to the other options. The basic and cephalic veins in the arm (Option A) are typically used for venous procedures, not arterial grafting. The saphenous vein in the leg (Option C) is also commonly used for grafting, but the internal mammary and internal thoracic arteries are preferred for their better outcomes. The radial artery in the arm (Option D) is less commonly used for grafting compared to the internal mammary and internal thoracic arteries.
